SACK-HOLDER.

SPECIFICATION forming part of Letters Patent No. 775,962, dated November29, 1904. Application filed May 16, 1904. Serial No. 208,146. (Nomodel.)

To (ti? m/tont it may concern.-

Be it known that I, ANDREW H. BEGKMAN,

a citizen of the United States, residing at (,i randy, in the county oflsanti and State of Minnesota, have invented certain new and usefulImprovements in Sack-Holders; and I do herebydeclare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention has for its object to provide an improved sack-holder, andto such ends it consists of the novel devices and combinations ofdevices hereinafter described,and defined in the claims.

The invention is illustrated in the accompanyihg drawings, wherein likecharacters indicate like parts throughout the several views.

Figure l. is a view in front elevation, showing the completesack-holder. Fig. 2 is a side elevation of the sack-holder, the sackbeing indicated by dotted lines. Fig. 3 is a plan view of thesack-holder. Fig. 4 is a detail in section on the line Jr .1 of Fig. 1,some parts being broken away; and Fig. 5 is a detail in front elevation,showing a portion of one of the sack-engaging grapple-irons andillustrating the manner in which the mouth of the sack is appliedthereto.

The numeral 1 indicates a pedestal or vertical support, which, asshown,is rigidly secured at its lower end to a base 2. At itsintermediate portion the pedestal 1 is formed with a slot 3, and rigidlysecured to the opposite edges of the upper portion of said pedestal is apair of 'ertically-extended guide-rods 4.

The numeral 5 indicates a pair of so-ealled grapple-arms, which workfreely through the vertically-elongated openings formed between theguide-rods4 and the pedestal 1 and are provided at their outer free endswith laterally-bentextensions 6. The arm extensions 6 project forwardfrom the pedestal 1 and rods 4, approximately parallel to each other,and are formed with vertically-projeeting barbs 7 for a purpose whichwill presently appear. ()ne of the arms 5 is formed with a trunnion 8,which projects through a perforation in the lower end of the other arm 5and works through the vertical slot 3 of the pedestal 1.

In this way the two grapple-arms 5 are pivotally connected at theirlower ends and are guided for vertical movements in the slot 3, so thattheir free ends will always project equal distances outward beyond theguide rods 1.

A ratchet-toothed grapple-supporting bar 9 is pivotally attached at itslower end to the projecting trunnion 8 of the said trunnionequipped arm5 and at its upper portion works freely through a yoke-likeloclolu-acket 10, rigidly secured on the upper end of the pcdestal 1.The transverse outer portion of the lock-bracket 10 engages as a detentwith the teeth of the bar 9 to support the same in any set verticaladjustment. A leaf-spring 11, secured on the back of the pedestal 1,presses against the bar 9 and yieldingly maintains engagement betweenthe teeth of the said bar and the transverse outer portion of the saidlock-bracket 10. The character indicates a sack, which sack is indicatedby dotted lines in Fig. 2 and is indicated in part by full lines in Fig.5.

To secure the sack with its mouth open in position for filling, the saidmouth or open end thereof is drawn outward over the extensions 6 of thegrapple-arms 5 and is turned inward and secured by the barbs T. Thisbeing done, the Weight of the sack will draw it downward on the freeends of the grapplearms and will cause the said arms to spread orseparate as far as they can by the mouth of the engaged sack, and inthis way the mouth of the sack is held open to its limit. The free endsof the grapple-arms being capable of considerable movement toward andfrom each other will adapt themselves to sacks varying considerably intransverse dimensions.

It is not desirable that a sack should be supported entirely from thegrapple-arms, because a sack when filled will be very heavy and willtend to tear itself loose from the barbs 7. On the contrary, it is verydesirable that the bottom of the filled sack be rested upon a rigidsupport. As is evident, by vertical adjustments of the ratchet-toothedsupporting-bar 9 the grapple-arms 5 may be vertically adjusted, so thatthe bottom of the sack will rest upon the base 2, with the sack heldelongated or drawn out to its full length.

This vertical adjustment of the grapple-irons should be given after thesack has been applied to the arm extension 6. A filled sack may bereadily released from the engaged mouth of the sack simply by pressingthe bar 9 slightly forward against its spring 11 and then downward, soas to lower the free ends of the grapple-arms.

The device described is of simple construction and is very easilyoperated. it is of course adapted to be used in all places where asack-holder is desirable, and is especially adapted for use inconnection with grain-delivery spouts of threslling-machines, elevators,and automatic grain-weighing devices.

The sackholder described capable of modification within the scope of myinvention as herein set forth and claimed.

b-at 1 claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. The combination with a supporting-ped I estal, having a verticalintermediate slot, and

parallel upper end guides, of a pair of grapple-arms working freelythrough said upper end guides, at trunnion pivotally connected to thelowerends of said grapple-arms, and working through the slot of saidpedestal, a ratchet- I toothed supporting-bar pivotally attached to ithe projecting rear end of said trunnion, and l a lock-bracket on saidpedestal, cooperating with said ratchet-toothed bar, to support saidgrapplc-arn'ls in d iiferent vertical adjustments, substantially asdescribed.

2. The combination with the pedestal Lhaving the vertical slot 3, andlaterally-projecting vertical guide-rods a, of the grapple-arms 5,working between said guide-rods 4 and said pedestal, and formed withlateral extensions 6, having barbs 7, one of said grapple-arms l havinga trunnion 8 pivotally connecting it to the cooperating grapple-arm,working through said slot 3 and projecting to the rear of said pedestal,the lock-bracket 10 secured l to the upper end of said pedestal, theratchettoothed bar 9, guided by and cooperating with said loclobracket.and pivotally attached to said trunnion 8, and the spring 11 yieldinglypressing the toothed portion of said bar 9 into interlocking engagementwith the said lockbracket 10, substantially as described.

In testimony whereof l ali'ix my signature in presence of two witnesses.
